I went and looked at the site for the mounting blocks that Electricmanscott suggested (they are like the ones I used before) and they worked well. I guess what I am after is more ideas along the lines of those from Dallas. I am wondering things like: with the code provisions that the box front be flush with combustible materials (and I must assume that vinyl is one of those materials) don't most of these type of installs require a box to be installed that is flush with the siding? Wouldn't that require cutting a rectangular hole in the siding? Or, do people drill a hole and install a nipple through it and connect the nipple to a box, if so do they just secure the light to the siding and whatever is under it with screws? Rob
